For example, when the display data received by the first gamma lookup table 112 and the second gamma lookup table 114 of the driver 110 is a solid color picture and the gray level is lower than or equal to the L32 gray level, the first gamma search is performed. The first pixel voltage V _M provided in Table 112 is equal to the second pixel voltage V _S provided by the second gamma lookup table 114, so that adjacent pixels (sub-pixels) will display the same brightness. In order to improve the plaid phenomenon and the overall picture color break, enhance the user's viewing experience on the display panel. In another embodiment, the threshold may be an L5 gray scale (in the embodiment, the gray scale range L0~L255 is taken as an example), but the case is not limited to the above critical value, and the method can be adaptively implemented according to the actual situation. Demand to choose the above threshold.

Figure 7 is a diagram showing verification data of an embodiment as shown in Figure 6 in accordance with yet another embodiment of the present invention.

For the influence of the above phenomenon, please refer to Figure 9. First, the ideal common voltage Vcom should be maintained at the same voltage value as shown in Figure 9. However, since the polarity of the main sub-pixels m on the same scanning line is positive, Once the data voltage provided by the data line D1 is turned to a high level, the common voltage Vcom will be pulled to the positive polarity, so that the cross-pressure of the main sub-pixel m becomes smaller, and the voltage across the sub-pixels becomes larger, resulting in a change of the gamma line. This causes horizontal crosstalk (H-Crosstalk).

In order to improve the above problems, the polarity of the data voltage provided by the data line is differently configured in the present case, so that the data signals received by the main sub-pixels in the same column include positive polarity and negative polarity, and not all positive polarity, so that the common voltage Vcom Maintain the same voltage value to improve the horizontal crosstalk phenomenon.

The positive polarity is such that the common voltage Vcom is maintained at the same voltage value, thereby improving the horizontal crosstalk phenomenon.

11A is a schematic diagram showing the polarity configuration of a data voltage according to another embodiment of the present invention. As shown in the figure, the polarity of the data voltage provided by each of the eight data lines is positive (+), negative (-), negative (-), positive (+), negative (-), positive. (+), positive polarity (+), and negative polarity (-), correspondingly, in the same column, the polarities of the data signals received by the main sub-pixels m and the sub-pixels s-arranged are positive. (+), negative polarity (-), negative polarity (-), positive polarity (+), negative polarity (-), positive polarity (+), positive polarity (+), and negative polarity (-). 11B is a schematic diagram showing the polarity of a display panel and its sub-pixels according to another embodiment of the present invention, wherein the sub-pixels of the same row can be transformed once every two columns, but not limited thereto, N can be used. Column polarity conversion. Figure 11B shows the state in which the polarity of the data voltage of Figure 11A is applied to the display panel. It can be seen from Figure 11B that the data signal received by the main sub-pixels in the same column contains positive and negative polarities, not all of them. The positive polarity is such that the common voltage Vcom is maintained at the same voltage value, thereby improving the horizontal crosstalk phenomenon.

FIG. 12A is a schematic diagram showing the polarity configuration of a data voltage according to another embodiment of the present invention. As shown in the figure, the polarity of the data voltage provided by each of the eight data lines is positive (+), positive (+), positive (+), positive (+), negative (-), and negative. Sex (-), negative (-), and negative (-), respectively, correspondingly, in the same column, the polarities of the data signals received by the main sub-pixel m and the sub-pixels staggered are positive. (+), positive polarity (+), positive polarity (+), positive polarity (+), negative polarity (-), negative polarity (-), negative polarity (-), and negative polarity (-). 12B is a schematic diagram showing the polarity of a display panel and its sub-pixels according to another embodiment of the present invention, wherein the sub-pixels of the same row are changed once every two columns, but not limited thereto, N columns may be used. Polarity conversion. Fig. 12B shows the state in which the polarity configuration of the data voltage of Fig. 12A is applied to the display panel. It can be seen from Fig. 12B that the data signal received by the main sub-pixel m in the same column contains positive polarity and negative polarity, but not all. It is positive polarity to maintain the common voltage Vcom at the same voltage value, thereby improving the horizontal crosstalk phenomenon.

In the embodiment of FIG. 10A to FIG. 12A, the data lines on both sides of the partial sub-pixel are of the same polarity, such as the data lines D1 and D2 of the 10A diagram are of the same polarity. (+), data line D3 and D4 have the same polarity (-), thus, will cause vertical crosstalk (V-Crosstalk), in order to improve the vertical crosstalk, this case is configured for the polarity conversion of the data line, please refer to the following 13 picture.

It can be seen that the configuration of the polarity conversion of the data line in this case can indeed improve the problem of vertical crosstalk. . In addition, the period of the dot polarity conversion should not be too large to avoid affecting the state of the liquid crystal, but instead lead to more display problems. According to this, the period of the polarity switching used in the present case is less than 1 millisecond (ms), and can not affect the liquid crystal. Under the condition, the average voltage of the common voltage Vcom is made constant to improve the problem of crosstalk in the vertical direction. In an embodiment, the N-line point polarity conversion can be used in this case. In order to avoid the period of the polarity switching, the liquid crystal state is affected.
